Why use a car preheater and why should the car be preheated? How do you warm up properly?

1. Start the engine smoothly at low temperature - this is the original purpose of people;

2. In order to save fuel - this is the unanimous desire of people;

3. In order to reduce the wear and tear of the running parts - this is people's upgraded understanding;

4. In order to protect the environment - this will surely become a common regulation of all countries in the world.

It is available in two types: a fuel preheater and an electronically controlled preheater, the latter of which uses a 220-volt power supply to raise the temperature of the engine by heating antifreeze water. The preheater consists of an electric heating element, a German magnetic steel water pump, an electric motor and a temperature control element. It is connected in series on the water tank line.

The electric heating element heats the antifreeze, and the water pump drives the heated antifreeze to circulate between the engine and the warm air. The temperature control element automatically shuts off the power supply when the water temperature reaches 70 degrees Celsius.

At present, the vast majority of electronically controlled preheaters are used.

It's hard to start the cold machine, so it's easy to start with a preheater...

If there is no garage in winter, the car will be as cold as ice cubes overnight when left outside, if it is a diesel car, it is difficult to ignite, the high idle speed of the cold car start, the fuel consumption is also very high, if the car preheater is used, the water tank and engine are heated in advance, the ignition is easy, and the cab is also warm! But don't think about that kind of plug-in.,Poor security.,In case of fire, the level outweighs the loss.

Recommend the German Weibostone, the temperature is controlled by the microcomputer, the water tank is automatically cut off and preheated to 81 degrees, and the mobile phone can also be started remotely, which is very convenient!

What are the benefits of a train for a car when it starts? Most people believe that when you need to use the car early in the morning, it is most beneficial for the car to idle the train in place after starting the car and wait for 3 to 5 minutes to operate normally. But are you sure this is the right way to warm up the car?

According to one statistic, more than 90% of partial damage to engine components occurs within 3 minutes of cold start. So, how can we do a good regional train, I believe this is a question that all car enthusiasts are concerned about. But before we go into detail about the train method, let's understand why exactly a car has to take a train.

You need to know the reason for the train to train normally. After a long shutdown of the first car, the oil in the engine flows back into the oil pan in the lower part of the engine. Therefore, when the engine is started after the car is not used for a long time, the upper part of the engine is in a situation where there is no oil and insufficient lubrication.

It takes about 30 seconds after starting to deliver the engine oil to the piston rod, crankshaft, engine crankshaft and other parts of the engine that need lubrication the most. However, if the engine starts normally as soon as it starts, if you don't force the fuel truck and keep it running at low speed, the actual effect may be the same as running at idle speed.

The oil system software provided before the engine reaches the operating temperature is still low, and it is not possible to properly vaporize the car's gasoline. Gasoline used in cars does not vaporize, it is a "wet click" liquid, and it is difficult to ignite, so start the engine. We now need to use the effect of the windshield to prevent some of the gas from entering the cylinder, increase the mixing cost of gasoline gas for vehicles, increase the engine speed, so that the engine does not stall.

Once all normal operating temperatures have been reached, the fully automatic windshield will naturally recover due to the posture of the mechanical equipment.

The lubrication of the transmission gears of the related transmission is actually the most incomprehensible and easy to ignore by ordinary people. The gearbox oil flows to the same area as the engine oil, and in the case of a cold car, the oil flows to the lower half of the gearbox. Only when driving, due to the operation of the electric gear, can oil from the bottom be brought to lubricate the top.

That's why most vehicles are astringent when changing gears on a cold car. Nor can it be disposed of by train in situ. The gearbox does not have a gear pump, so the in-place train can only move the engine, and some of them do not move, so the situation can only be improved by gradually driving from the facts.

Idling a train in place is really not necessary. Because the actual effect is relatively limited, it is a luxury to waste car gasoline and time (plus air pollution). In addition, when the engine is idling at an idle speed, there is a case that carbon accumulates in automobile gasoline due to high temperatures, which can further damage the engine.

The correct train method of the car should start normally 30 seconds to 1 minute after starting, and the train time can be appropriately increased in low temperature areas. When the car is just started, it is absolutely not to spin the car at high speed, it must be kept low and the engine speed should not exceed 3000 3500 rpm. That generally stays at 2000 rpm, otherwise the engine and transmission suffer considerable losses.

Preheating is to warm up the car, one is to make the lubricating oil fully work, the other is to increase the working temperature of the engine, reduce the loss of the car. Start the car for 30 seconds and then start to achieve the effect of hot car.

We are typing the answer by hand, so please be patient for a while. I'll give you a solution in a few minutes, thanks! ❤️

It is best to preheat and then start the car needs to be warmed up, because the temperature of the engine that has just started is low, and the lubricating oil in each part is not in place. The warm-up time does not need to be too long, ask questions.

My car is starting, and the sound is very loud during the start in the morning, as if the oil can't keep up, the sound is loud and small, and my car didn't need to be warmed up before.

Now the car can't go without warming up.

I feel like the car still costs gas.

Mine is a BMW 2 Series 218i

Seven-seater car. Your situation is no longer a warm-up issue.

Caused by an over-dilute engine mixture.

Questions. The warm-up is good, and the normal driving does not feel different.

It is normal for you to warm up, but if you don't warm up, there will be a lot of noise, and the waste oil should be caused by a loose throttle gap.

The gap needs to be adjusted to allow the mixture to mix.

The preheating of the car is to let the engine get used to it, so that it will not work without starting to use it, which will damage the engine. Generally, it takes 10 minutes to insert the key.

Today's cars basically don't need to be preheated, don't rush to the gas pedal when the car is cold, but compared to the early cars still have to be preheated, the general car can be preheated for 3 or 5 minutes.

The role of the car preheater:

1. Heat the antifreeze in winter to improve the starting speed of the car;

2. In the case of low temperature in winter, maintain the temperature of the engine block of the car when it is not in use.

3. The preheater can also preheat the oil, so that the oil at the start of the engine can keep the original smooth, and can immediately circulate in the whole engine.

The car preheater realizes that the car does not need to heat the garage in winter, eliminating the trouble of starting after parking in winter. Even in the freezing cold of minus 30 degrees, you can go as you like and travel at any time. When the car reaches the starting temperature, it will automatically stop heating and the power indicator will automatically turn off, so that your car can always walk with you.

Here are a few points that should be paid attention to in car preheaters.

Introduction to Automotive Preheaters: Introduction.

The function of the automobile engine preheater is to heat the automobile engine at low temperature, and at the same time heat the empty chamber of the automobile and defrost the troubleshooting window. The heat source of the car engine preheater comes from burning gasoline and can be used after the engine is turned off, or it can be used as paving heating while driving.

The water pump attached to the engine preheater of the automobile pumps out the antifreeze in the engine body, heats it through the automobile engine preheater, and then circulates it into the engine body, heats the engine, and starts the engine at a low temperature.

Introduction to automotive preheaters: principle.

Under the impact of the high-speed updraft, the raw meal fed into the preheater pipe is flipped upwards and moves with the air current, while being dispersed. The distance from the drop point of the material to the turning point (suspension distance) and the degree of material dispersion depend on the air velocity, the nature of the material, the gas-solid ratio, the equipment structure, etc. Therefore, in order to make the material evenly and quickly disperse and suspend in the riser, the following problems should be noted:

1) Select a reasonable feeding position, with the help of the length of the riser, fully extend the heat exchange time between the material and the gas, and the feeding point should be close to the beginning of the inlet pipe, that is, the beginning of the air outlet inner cylinder of the next cyclone. However, it must be based on the premise that the added material can be fully suspended and does not fall directly into the next preheater (short circuit).

Well, that's all for today's car profile. I hope that the working principle of the preheater briefly introduced by the car today can be helpful to all friends. If you still want to know more about you, let's follow this**.

Hundreds of quietly envy car purchase subsidies.

1. The function of the automobile engine preheater is to heat the automobile engine at low temperature, and at the same time heat the interior space of the automobile and help defrost the window. The heat source for the car engine preheater comes from the combustion of gasoline and can be used when the engine is turned off or as an auxiliary heating during driving.

2. You don't need to start the engine, you can warm up the engine and the car in advance at the same time, so that people can open the door in the cold winter and enjoy the warmth of home.

3. It is more convenient to pre-let Duan Zi heat, and the advanced remote control and timing system can easily heat the car at any time, which is equivalent to having a warm storage with the car.

4. Avoid wear and tear on the engine caused by low temperature cold start. Studies have shown that engine wear from a single cold start is equivalent to a vehicle's normal driving of 200 km, and 60% of engine wear is due to cold starts. Therefore, the installation of a car engine preheater can fully protect the engine and extend the service life of the engine by 30%.

The use of a car preheater is equivalent to driving 300 kilometers of wear and tear. In cold areas, the hazard of low temperature start of the engine has been bothering people, the cab is cold and biting, the windshield is frosty, affecting driving safety, low temperature cold start, difficult to start or even unable to start, the engine cold start once, quite normal driving 300 kilometers of wear and tear, emissions seriously exceed the standard.

The composition of the automobile preheater includes:

1. preheater middle plate left side top has groove, and described groove is fixed with heating body.

2. a thermostat is installed below the heating body.

3, thermostat is fixed in the circular groove of preheater middle plate, described preheater middle plate right side is connected with water pump device by bolt, described water pump device top has rotor, described preheater middle plate top two sides are connected with preheater upper shell by bolt, described preheater middle plate bottom is connected with preheater lower housing by stop mouth, and the utility model is used for automobile preheater.

4. In winter, heat the antifreeze and stop liquid to improve the starting speed of the car; In the case of low winter temperatures, the temperature of the engine block of the car is maintained when the car is not in use, and the preheater can also preheat the oil, so that the oil at the start can maintain the original smoothness and can immediately circulate throughout the engine.

In winter, do I need to warm up the car after starting the engine? Yes, the car should be idle to warm up after starting.

Generally speaking, after the engine has been standing overnight, the residual pressure of the lubricating oil on each friction surface has long disappeared, and the oil film protection has been lost; The low temperature greatly increases the viscosity of the lubricating oil, and the adhesion and fluidity become poor. At this time, the movement resistance of the starting engine is greatly increased, and more than 60% of the power at the start is used to overcome the movement resistance of the cold engine. Authoritative research results show that the chiller needs to be preheated.

The amount of wear on the engine during cold starts is about the same as in other operating conditions. In other words, the amount of wear on the engine during cold start accounts for about half of the total wear. Normal idle warm-up can reduce this wear and tear and extend the life of the engine.

At low temperatures, the metal exhibits less elasticity and wear resistance; Only at operating temperatures can the engine achieve normal mating clearance and maintain optimal working condition.

After starting the engine at a low temperature, start and walk the car. Due to the uneven mixing ratio, the engine output power is insufficient; At low temperatures, the fuel with insufficient atomization cannot be fully combusted, and carbon deposits are easy to form; Some gasoline is not atomized, and it will flow directly along the cylinder wall and travel into the crankcase to mix with the oil, reducing the quality of the oil. But the longer the stool, the better.

If the car is heated for a long time, the engine will be useless and waste fuel, which is not conducive to environmental protection. Under normal circumstances, it is advisable for low-end cars to be able to idle normally. The normal idle speed is reduced from 1200rpm in the fast idle state to 800rpm, and you can walk the car just by looking at the tachometer normally.

Warm-up is not only the release of the land-based motor, but also the gearbox. In the cold state, multiple starts should be avoided, because multiple starts will aggravate the wear of moving parts and reduce the overall working life of the parts and even the engine.
